i STORAGE-BATTERY TERMINAL.

Application filed May 9,

p This invention relates to improvements in devices used to attach the current carrying cables to the binding posts of storage batteries the-common type used in connection with gas-engine ignition.

The principal objects of my invention are to provide a terminal device for the above named purpose so constructed that it will not corrode as the usual terminal clamps do; and one from which the cable may be easily disconnected from the battery without the use of tools and without removing the terminal as a whole, and hence without the liability of twisting off the binding post, or otherwise damaging the same and the terminal member, as commonly occurs with the ordinary form of terminal.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects .I accomplish by means of such structure and relative arrangement of parts as will fully appear by'a. perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

' Fig. 1 is a top plan view of my improved terminal.

Fig. 2 is a sectional elevation of the same, and

Fig. 3 is an end view of the device.

Referring now more particularly to the characters of reference thereon, the numeral 1 denotes a lead ring or sleeve adapted to snugly fit on a battery post 2 and to be then permanently fastened thereon, as by sweating with solder or other suitable means. Formed integral with the sleeve 1 is another sleeve 3, to oneside of the former, and disposed with its axis at right angles to that of the ring.

Snugly fitted into the sleeve 3 from the opposite ends thereof are compressed carbon bushings' i, having enlarged shouldered portions 5 at their outer ends which abut against the adjacent faces of the sleeve.

Removably mounted in the bushings 4 is a brass stem 6. One end of this stem is formed with a socket member 7 to receive one end of a current-carrying cable 8, which is permanently secured therein in any suitable manner. A. flange 9 at the inner end of 1924, Serial No. 712,153.

tery when desired, it is only necessary to remove the nut 10, when the stem 6, with the cable attached thereto, may he slid clear of the bushings 4:. without disturbing or removing the terminal as a whole. The metal stem 6 is nowhere in contact with the metal sleeve 3 or post 2, and the current from or to the latter and the cable 8 must therefore pass through the carbon bushings interposed between the sleeve and stem.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A battery terminal device including a metal sleeve adapted to be connected to a battery post, carbon bushing means in said sleeve, and a metal stem adapted for con nection to a cable, inserted in the bushing means and contacting therewith.

2. A battery terminal device including a metal sleeve adapted to be connected to a battery post, carbon bushing means in said sleeve, a metal-stem adapted for connection to a cable, inserted in the bushing means and contacting therewith, and means for removably securing said stem in place.

3. A battery terminal device including a metal sleeve adapted to be connected to a battery post, carbon bushing means in said sleeve, a metal stem adapted for connection to a cable, inserted through the bushing means, a member formed with said stem and abutting against the bushing means at one end thereof, a removable nut on the other end of the stem for clamping the latter in place, and means preventing contact of said nut with the metal sleeve.

4. A battery terminal device including a metal sleeve adapted to be connected to a battery post, carbon bushing means in said sleeve, a metal. stem projecting through the.

bushing means, the latter projecting beyond the metal sleeve at both ends, a socket memher for receiving one end of a cable incorporated with the stem and abutting against one end of the bushing means, and removable means on the other end of the stem and contacting with the adiacent end of the bushing means for holding the stem in place and engaged with the carbon.

5. A battery terminal comprising a metal sleeve adapted to be fixed on a battery post, another sleeve formed with the first sleeve and disposed in a plane at an angle thereto and to one side thereof, carbon bushing means in said last named sleeve, and a metal stem adapted for connection to a cable, removably mounted in the bushing means and contacting therewith.

In testimony whereof I afiix my signature.
